Plastic Balls Wholesaler shares plastic polishing methods
1. Mechanical polishing Mechanical polishing is a polishing method that obtains a smooth surface by cutting and plastic deformation of the material surface to remove the polished convex parts. Generally, whetstone strips, wool wheels, sandpaper, etc. are used, mainly by manual operation, and special parts such as rotation On the surface of the body, auxiliary tools such as a turntable can be used. If the surface quality is high, the super-precision grinding method can be used. Super-precision grinding and polishing is the use of special grinding tools, in the grinding and polishing liquid containing abrasives, tightly pressed on the surface of the workpiece to be processed for high-speed rotation. The surface roughness of Ra0.008μm can be achieved by this technology, which is the highest among various polishing methods.
3. Electrolytic polishing The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, by selectively dissolving the tiny protruding parts on the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better.
4. Ultrasonic polishing Put the workpiece in the abrasive suspension and put it in the ultrasonic field together, relying on the oscillation of the ultrasonic wave to make the abrasive grinding and polishing on the surface of the workpiece. Ultrasonic processing has a small macro force and will not cause deformation of the workpiece, but tooling is difficult to manufacture and install. Ultrasonic processing can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is added to stir the solution to dissolve the dissolved products on the surface of the workpiece, and the corrosion or electrolyte near the surface is uniform; the cavitation effect of ultrasonic waves in the liquid can also inhibit the corrosion process, which is beneficial to the surface brightening.
